BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 699,661, dated May 13, 1902.

Application filed June 1,1901.

To ZZ whom it 71mg/ concern.-

Be it known that I, THOMAS J. Comune, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have inventedl new and useful Improvements in Ealing-Presses, of which the following is a specilication.

My invention relates to rebounding-plunger baling-presses; and the object of my invention is to improve the press forming the subject of Letters Patent No. 651,830, issued to myself.

One of the specific objects of the present invention is to provide means for holding the plunger-chain upon the teeth of the-wheel around which it passes, and I attain this object by employing a sprocket or block chain in lieu of an ordinary-chain and employing a wheel with sprocket-teeth for engaging the chain, also a spring for holding the chain against the lower part of the sprocket-wheel.

Another special object of my invention is to produce an improved device for releasing the chain twice at each revolution of the sweep.

A further object is to produce an adjustable tension device for engaging the horizontal plate secured to the plunger-head, whereby the plunger-head is prevented from recoiling from its initial or starting position.

I'Vith the above and other objects in view my invention consists in the novel construction and arrangement of parts described hereinafter and represented in the accompanying drawings, in which- Figure 1 is a partly-sectional side elevation of a press constructed in accordance with my invention, a portion of the baling-chamber and of the plunger-shield being broken away. Fig. 2 is a plan view of the press, omitting the power-head and the sweep, the balingchamber broken away. Fig. 3 is an enlarged end View of the detachable and reversible hopper. -Fig. l4 is a partly-sectional View showing the .plunger tension device. Fig. 5 is an enlarged transverse section of the reach and the rod-coupling. Fig. 6 is a brokenaway plan view of the bed-plate, showing the trip-cam, the parts above being removed, one position of the chain-cam being shown in dotted lines. Fig. 7 is a vertical section through the chain-cam and its connected and Serial No. 6 2,69 1. (No model.)

adjacent parts, taken on a line corresponding to line VII VII of Fig. 6, omitting the axle, and showing one of the dogs not in section. Fig. 8 is a plan view of the vsweep-head detached, the sweep being broken away. Fig. 9 is a transverse section of the chain-cam detached, taken on line IX IX of Fig. 7, showing also the shackle engaging the cam. Fig. 10 is enlarged broken-away view of the rodcoupling, the reach being in section.

1 designates the main frame ot"` the press, which frame is of the usual form,;except in the modification described hereinafter, and the bale-chamber is also of the usual form, only a portion of which being shown in the drawings. A

The reach 2, made, preferably, of wood, is secured to the frame l by stirrups 3 and terminates in a metal bed-plate 4, described hereinafter. The bed-plate may be supported by wheels 5 or may be placed directly on the ground or floor.

Rigidly secured to the plunger-head G are two approximately horizontal bars 7, connected near their outer ends by a stout pin 8, on which is mounted an antifriction-roller 8 between said bars. The plunger-chain 12, through which the plunger is forced into the bale-chamber, is connected to pin 8 by side links, as shown in Fig. Said chain passes around an elliptic sprocket-wheel 9, mounted eccentrically upon a cross-shaft 13, j ournaled in castings 14 14, bolted to the horizontal longitudinal bars of the frame 1, adjacent to the baling-chamber. The chain 12 is connected by rods 15 15 to a chain 16, which is connected to a shackle 17, which loosely embraces the flanged edge of the chain-cam 18. (See Figs. 2 and 9.) As shown in Figs. 2, 7, and 9, both the upper and the lower face of cam 18 are provided with a peripheral iiange, the function of which is to engage antifriction-rollers 17', carried by the shackle 17, so that the chains 12 and-16 may be pulled back by means ot a dog 19 or 19' when the chaincam is rotated, as will now be described. Said dogs are elongated rectangular bars mounted slidably in radial slots formed in the chain-cam 18, as shown in Fig. 7 and indicated by dotted lines in Fig. 6. When either dog is fully retracted within the cam 18, its outer end is iiush with the cam periphery, as

ICC)

L cured in) the stationary trip-cam 23, preferably cast integral with the bed-plate 4, as

shown. The function of said trip-cam 23 is vto engagedepending studs 24, secured to the respective dogs 19 19', so that when the chaincam 18 is rotated the dogs 19 19 will be alternately drawn into said cam and projected therefrom, this motion being effected by a recess 23 in the stationary cam 23 cooperating with a small auxiliary cam 25, so placed and formed as to positively cause cach stud 24 in succession to pass 'between itself and cam 23, thereby withdrawing the dogs 19 19' alternately and forcing each one outwardly again when its stud passes the recess in the cam 23. The chain-cam 18 is rotated in the direction of the arrow, and the shackle 17 is engaged by one of the dogs 19 19 during a half-rotation of the chain-cam 18. During this motion the chains 12 16 are pulled around the chain-cam, and when the shackle 17 has been pulled around one hundred and eighty degrees, to

the point farthest from the bale-chamber, the

vcharge of material is fully compressed. The

dog 19 is immediately retracted by cams 23 25, therebyreleasing the shackle 17, which flies back toits starting position. (Shown in Fig. 2.) This return is effected by springs or other suitable devices (not shown) connected to the plunger-head 6. When the shackle flies back to its initial position, it is immediately engaged by the other dog 19', which is projected from the chain-cam by cani 23, as already described. When the shackle reaches the half-way point, it is again released, as described, and hence the plungerhead is withdrawn twice during every revolution of the chain-cam 18. 1t will be observed that the center of rotation of the chain-cam 18 is not in alinement with the rods 15 15'. The purpose of setting the stub-shaft 22 at one side, as shown, is to cause the chain to be pulled in a straighter line than if the center of rotation were in the center of the bedplate 4.

yThe sweep-head 26, shaped, preferably, as shown in Fig. 8, rests upon the cam-hub 21 and has two shoulders which fit recesses 21 in said hub. A bolt 27, extending through the head 26 andthe stub-shaft 22, holds said parts together, and the head 26 maybe further secured to the cam-hub 2l by screws, as 28, Fig. 8. The sweep maybe secured to the head 26 in any of four different positions, as will be apparent by reference to Fig. 8.

The eccentric elliptical sprocket 9 is so adjusted that when the chain 12 reaches the end of its pull it acts on the longest radius of the sprocket, and hence exerts the greatest leverage upon the plunger-bars 7 The combination of the sprocket-wheel and sprocket-chain prevents the chain from becoming disengaged from the Wheels, and as an additional safeguard I employ a flat spring 30, Fig. 1, which holds the chain up against the sprocket. Adjacent to the sprocket is a guide or cap 29, secured to the reach 2, for preventing lateral movement of chain 12 when the plunger-head rebounds.

Referring to Figs. 5 and 10, the pivotal connection between the rods 15 and 15 is formed by two links 31 32, connecting eyenuts 33 on the ends of said rods. The bottoni link 32 forms a shoe which travels in a shallow groove cut in the upper face of the reach 2, and said shoe is retained therein by two longitudinal plates 34, secured to the reach.

A protecting-cap 35, of sufficient length to always cover the connecting members just described in' any position of the latter, is sccured to the plates 34, as shown in Figs. 1 and 2. A longitudinal rib or stop 36 is secured to the reach 2 for stopping chain. 16 in al straight line when the shackle 17 flies back to starting position, which if it did occur, owing to the momentum of the chain, would tendto cause the plunger-head to recoil from its starting position.

For preventing the plunger-head from recoiling when it flies back to its starting'position I employ the devices shown in Figs. 2 and 4. 37 designates the usual shield or plunger-plate secured to the plunger-head. This shield underlies the longitudinal T or angle bars 38 at the top of the frame 1 and is held in contact with the ends of said bars by a pair ofplates 39, the inner port-ions of which are secured to the top of the shield at their inner portions, but are bent upwardly, as shown in Fig. 4, so that their outer edges rest upon the bars 38, and grooves are thus formed between said plates and the shield 37 for the fianges of said bars. A transverse bolt 41 extends through the vertical flanges of the frame-bars 38, and it will be readily understood that when said bars are slightly drawn together by tightening said bolt the inner flanges of said bars will enter more closely the grooves formed between plates 38 and the shield 37, and the friction between the4 shield and said frame-bars will be increased. This friction should be only sufficient to prevent recoil of the plunger-head into the feedchamber, and it may be adjusted readily by turning the nut on the bolt 4l.

The hopper 42 is detachable and reversible, so that material to be baled may be pitched therein to from either side of the press, and to this end is constructed as shown in Figs. 1, 2, and 3, from which it will be seen that the hopper has only three sides or two short sides and a back, with an opening at one side to facilitate pitching the material into the hopper.

In Fig. 3, 38 designates the upper longitudinal bars of the bale-chamber in section. The lower edge of the back of the hopper is provided with a recurving lip 43, which IOO IOS

IIO

engages the horizontal iiange of bar 3S. The open side or front of the hopper is detachably secured to the other frame-bar 38 by two depending hooks 44E, one of which is shown in Fig. 3. Vhen the hooks engage the frame-bar 38, as shown, the hopper is rigidly secured in position. lVhcn the hooks are swung out, the hopper may be removed from the feed-chamber. To reverse the hopper with relation to the feed-chamber, the hooks 44 are disengaged from the frame-bars 3S, the lip 13 is disengaged from the other bar 38,the hopper is lifted and turned around, so that its open side is at the opposite side of the press, the lip 43 is slipped over the other frame-bar 38, and the hooks 44 are turned down to engage the other bar 38, thereby securing the hopper in position.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a baling-press, a bed-plate located at the end opposite the bale-chamber, a tripcam 23 rigidly secured to the upper face of the bed-plate, an upright stub-shaft rigidly secured to said trip-cam, a substantially elliptical cam 1S mounted rotatably on said stub-shaft, a sweep for rotating said cam, a

pair of dogs lying within slots in said cam,

parallel tothe longest axis of said cam, in opposite ends thereof, a stud secured to each dog, and engaged by said trip-cam, whereby the outer ends of said dogs normally project beyond the periphery of said cam 1S, an upwardly and a downwardly projecting peripheral flange on said cam, a shackle having antifriction-rollers engaging said flanges, a recess 23 in said trip-cam, and an auxiliary cam 25 adjacent to said recess for pulling each of said dogs inwardly in succession, thereby releasing said shackle when either of the aforesaid studs is engaged by said auxiliary cam; a plunger, and tension members between the plunger and said shackle; substantially as described.

2. In a baling-press, the combination, with the reach, having a longitudinal groove in its upper face, of a plunger-actuating chain 12, a rod connected thereto, a companion rod, a pivotal connection between said rods, comprising a pair of links, the lower of said links lying in said groove in the reach, retainerplates secured to the reach above said lower link, a cap secured to said plates above the path of said links, a chain 16 connected to the last-named rod, a forked shackle connected to said chain, a`cam having an upwardly and a downwardly projecting peripheral iiange engaged by the arms of said shackle, a movable projection on said cam for engaging said shackle, and a longitudinal projection secured lto the 'reach at one `side the chain 16, for preventing said chain from forming slack therein when `it is released from said cam; substantially as described.

3. In a baling-press, the combination, with the plunger plate or apron 37, of plates 39 secured thereto at their inner portions and having their outer portions free, to form grooves with said plunger apron or plate, frame-bars 3S having flanges entering said grooves, and transverse bolt passingthrough said frame-bars for drawing them together into frictional engagement with said grooves; substantially as, and for the purpose, specified.

el. In a baling-press, in combination with angle-bars 38 of the bale-chamber frame, a reversible hopper comprising a hopper, a lip secured thereto for engaging one of said angle-bars, and depending hooks secured to the respective sides of the hopper, for engaging the opposite angle-bar; substantially as de' scribed.

In testimony whereof I aiiix my signature in the presence of two witnesses. p
